Adjusting Volume of a Videoconference Using Touch-Based Gestures

ABSTRACT

Controlling a videoconference based on gestures received to a touch interface. A gesture may be received to a touch interface. In response to the gesture, a videoconference action may be performed. For example, a first gesture may be received to mute the videoconference and in response, the videoconference may be muted. As another example, a second gesture may be received to adjust the volume of the videoconference, and the volume may be correspondingly adjusted. Further, various gestures may be received for controlling one or more cameras in a videoconference, accessing settings in a videoconference, interacting with a presentation, etc.

FIELD OF THE INVENTION

The present invention relates generally to conferencing and, more specifically, to controlling a videoconference.

DESCRIPTION OF THE RELATED ART

Videoconferencing may be used to allow two or more participants at remote locations to communicate using both video and audio. Each participant location may include a videoconferencing system for video/audio communication with other participants. Each videoconferencing system may include a camera and microphone to collect video and audio from a first or local participant to send to one or more other (remote) participants. Each videoconferencing system may also include a display and speaker to reproduce video and audio received from remote participant(s). Each videoconferencing system may also be coupled to a computer system to allow additional functionality into the videoconference. For example, additional functionality may include data conferencing (including displaying and/or modifying a document for both participants during the conference).

Initial videoconferencing systems generally used a remote control to control videoconferencing functionality. However, as videoconferencing has become more prevalent, the number of desired and supported features has increased greatly. Unfortunately, the interfaces used to control videoconferences have not been able to keep up the increase in features, leading to a confusing and inefficient user interaction. Accordingly, improvements in videoconferencing control are desired.

SUMMARY OF THE INVENTION

Various embodiments are presented of a system and method for controlling a videoconference using a touch interface.

Initially, a first gesture may be received to the touch interface. The first gesture may be any of various types of gestures, but may generally be a complex gesture (one that involves more than a simple single touch tap gesture). Additionally, the first gesture may be received to the touch interface in any of various manners. For example, the touch interface may include a graphical user interface for controlling a videoconference or a videoconferencing system. The user may interact with the graphical user interface by performing a tap gesture to select various options displayed in the graphical user interface. In one embodiment, the first gesture may be performed over the graphical user interface and, e.g., may be independent from the various options presented in the graphical user interface, as described below.

In response to the first gesture, a first videoconference action may be performed. For example, the touch interface may receive the gesture in and then provide an indication of the gesture to the videoconferencing system (e.g., to a videoconferencing unit of the videoconferencing system).

The particular combination of gesture and videoconference action may be any desired combination. As discussed below, the gesture and action may relate to performing various volume control actions, muting, controlling a videoconference camera, and/or accessing settings (e.g., administrative settings for the videoconference or videoconferencing system), among other possibilities. Other pairings are envisioned and may be used for any desired videoconference action.

According to various embodiments, the first videoconference action may be determined based only on the first gesture itself. More specifically, the first videoconference action may be determined from the first gesture independent from a graphical user interface (or any information) displayed on the touch interface. For example, the graphical user interface may currently display options for presentations and the first gesture may be for muting the videoconference (although any other videoconference actions are possible). Accordingly, despite the context of the graphical user interface, the first gesture may perform the mute action. Thus, in this embodiment, the first videoconference action may be determined independent from the information displayed on the touch interface.

Alternatively, the first videoconference action may be based on the context of the first gesture. For example, the first gesture may be associated with a plurality of different actions and the method may determine which of the actions based on the context of the first gesture. Following the example above, the first gesture may be associated with a presentation (e.g., to move forward or back in a presentation) but may also be associated with a different action, e.g., controlling a camera. Accordingly, the method may determine that because a presentation is currently being given, because the current graphical user interface relates to presentations, etc. the first gesture is to perform the presentation action rather than the camera control action. The context may include whether the user input is received during a videoconference, whether the user input is received during a presentation, whether the user input is received during boot time or start up time of the videoconferencing system, a current graphical user interface (e.g., of the touch interface or of the videoconferencing display), a current menu being displayed (e.g., based on the subject of the menu, such as a presentation menu, in call menu, settings menu, participants menu, etc.), etc. Thus, in some embodiments, the videoconference action that is performed may be determined based on the context in which the first gesture was received.

Thus, in response to a gesture, a videoconference action may be performed.

FIG. 1—Exemplary Participant Locations

FIG. 1 illustrates an exemplary embodiment of a videoconferencing participant location, also referred to as a videoconferencing endpoint or videoconferencing system (or videoconferencing unit). The videoconferencing system 103 may have a system codec 109 to manage both a speakerphone 105/107 and videoconferencing hardware, e.g., camera 104, display 101, speakers 171, 173, 175, etc. The speakerphones 105/107 and other videoconferencing system components may be coupled to the codec 109 and may receive audio and/or video signals from the system codec 109.

In some embodiments, the participant location may include camera 104 (e.g., an HD camera) for acquiring images (e.g., of participant 114) of the participant location. Other cameras are also contemplated. The participant location may also include display 101 (e.g., an HDTV display). Images acquired by the camera 104 may be displayed locally on the display 101 and/or may be encoded and transmitted to other participant locations in the videoconference. In some embodiments, images acquired by the camera 104 may be encoded and transmitted to a multipoint control unit (MCU), which then provides the encoded stream to other participant locations (or videoconferencing endpoints).

The participant location may further include one or more input devices, such as the computer keyboard 140. In some embodiments, the one or more input devices may be used for the videoconferencing system 103 and/or may be used for one or more other computer systems at the participant location, as desired.

The participant location may also include a sound system 161. The sound system 161 may include multiple speakers including left speakers 171, center speaker 173, and right speakers 175. Other numbers of speakers and other speaker configurations may also be used. The videoconferencing system 103 may also use one or more speakerphones 105/107 which may be daisy chained together.

In some embodiments, the videoconferencing system components (e.g., the camera 104, display 101, sound system 161, and speakerphones 105/107) may be coupled to a system codec 109. The system codec 109 may be placed on a desk or on the floor. Other placements are also contemplated. The system codec 109 may receive audio and/or video data from a network, such as a LAN (local area network) or the Internet. The system codec 109 may send the audio to the speakerphone 105/107 and/or sound system 161 and the video to the display 101. The received video may be HD video that is displayed on the HD display. The system codec 109 may also receive video data from the camera 104 and audio data from the speakerphones 105/107 and transmit the video and/or audio data over the network to another conferencing system, or to an MCU for provision to other conferencing systems. The conferencing system may be controlled by a participant or user through various mechanisms, such as a touch interface described herein. The touch interface may be implemented as a remote control, as a portion of the speakerphones 107 and/or 105, and/or in any other desired manner. FIGS. 2 and 3 provide exemplary embodiments of such an interface.

In various embodiments, the codec 109 may implement a real time transmission protocol. In some embodiments, the codec 109 (which may be short for “compressor/decompressor” or “coder/decoder”) may comprise any system and/or method for encoding and/or decoding (e.g., compressing and decompressing) data (e.g., audio and/or video data). For example, communication applications may use codecs for encoding video and audio for transmission across networks, including compression and packetization. Codecs may also be used to convert an analog signal to a digital signal for transmitting over various digital networks (e.g., network, PSTN, the Internet, etc.) and to convert a received digital signal to an analog signal. In various embodiments, codecs may be implemented in software, hardware, or a combination of both. Some codecs for computer video and/or audio may utilize MPEG, Indeo™, and Cinepak™, among others.

In some embodiments, the videoconferencing system 103 may be designed to operate with normal display or high definition (HD) display capabilities. The videoconferencing system 103 may operate with network infrastructures that support T1 capabilities or less, e.g., 1.5 mega-bits per second or less in one embodiment, and 2 mega-bits per second in other embodiments.

Note that the videoconferencing system(s) described herein may be dedicated videoconferencing systems (i.e., whose purpose is to provide videoconferencing) or general purpose computers (e.g., IBM-compatible PC, Mac, etc.) executing videoconferencing software (e.g., a general purpose computer for using user applications, one of which performs videoconferencing). A dedicated videoconferencing system may be designed specifically for videoconferencing, and is not used as a general purpose computing platform; for example, the dedicated videoconferencing system may execute an operating system which may be typically streamlined (or “locked down”) to run one or more applications to provide videoconferencing, e.g., for a conference room of a company. In other embodiments, the videoconferencing system may be a general use computer (e.g., a typical computer system which may be used by the general public or a high end computer system used by corporations) which can execute a plurality of third party applications, one of which provides videoconferencing capabilities. Videoconferencing systems may be complex (such as the videoconferencing system shown in FIG. 1) or simple (e.g., a user computer system with a video camera, input devices, microphone and/or speakers). Thus, references to videoconferencing systems, endpoints, etc. herein may refer to general computer systems which execute videoconferencing applications or dedicated videoconferencing systems. Note further that references to the videoconferencing systems performing actions may refer to the videoconferencing application(s) executed by the videoconferencing systems performing the actions (i.e., being executed to perform the actions).

The videoconferencing system 103 may execute various videoconferencing application software that presents a graphical user interface (GUI) on the display 101. The GUI may be used to present an address book, contact list, list of previous callees (call list) and/or other information indicating other videoconferencing systems that the user may desire to call to conduct a videoconference. The GUI may also present options for recording a current videoconference, and may also present options for viewing a previously recorded videoconference.

Note that the videoconferencing system shown in FIG. 1 may be modified to be an audioconferencing system. For example, the audioconference could be performed over a network, e.g., the Internet, using VOIP. The audioconferencing system, for example, may simply include speakerphones 105/107 and the touch interface described herein, although additional components may also be present. Additionally, note that any reference to a “conferencing system” or “conferencing systems” may refer to videoconferencing systems or audioconferencing systems (e.g., teleconferencing systems). In the embodiments described below, the conference is described as a videoconference, but note that the methods may be modified for utilization in an audioconference.

FIGS. 2A and 2B—Coupled Conferencing Systems

FIGS. 2A and 2B illustrate different configurations of conferencing systems. The conferencing systems may be operable to perform the methods described herein. As shown in FIG. 2A, conferencing systems (CUs) 220A-D (e.g., videoconferencing systems 103 described above) may be connected via network 250 (e.g., a wide area network such as the Internet) and CU 220C and 220D may be coupled over a local area network (LAN) 275. The networks may be any type of network (e.g., wired or wireless) as desired.

FIG. 2B illustrates a relationship view of conferencing systems 210A-210M. As shown, conferencing system 210A may be aware of CU 210B-210D, each of which may be aware of further CU's (210E-210G, 210H-210J, and 210K-210M respectively). CU 210A may be operable to perform the methods described herein. In a similar manner, each of the other CUs shown in FIG. 2B, such as CU 210H, may be able to perform the methods described herein, as described in more detail below. Similar remarks apply to CUs 220A-D in FIG. 2A.

FIGS. 3A and 3B—Exemplary Touch Interface

FIG. 3A illustrates an exemplary touch interface and FIG. 3B illustrates an exemplary speaker phone with a touch interface. In the embodiment of FIG. 3A, the touch interface may be used as a remote control for a videoconferencing system, such as the videoconferencing system of FIG. 1. In the embodiment of FIG. 3B, the touch interface may be integrated in a phone, such as a speaker phone. In this embodiment, the touch interface may replace the typical physical button interface of the speaker phone, although additional physical buttons may also be present. Similarly, while the touch interface of FIG. 3A does not include physical buttons, embodiments are envisioned where physical buttons are also included. In some embodiments, the touch interface of FIG. 3B may be removable from the speaker phone (e.g., resulting in the touch interface of FIG. 3A), so that a user may separate the touch interface from the phone and use it as a remote control. The videoconferencing system of FIG. 1 may include a single touch interface (integrated in a speaker phone or not), or may include a plurality of touch interfaces (e.g., integrated with each of the speakerphones of the videoconferencing system). Additionally, the touch interface may be an explicit component of the videoconferencing system (e.g., as a speakerphone) or may be separate, but usable with the videoconferencing system. For example, a user's tablet or smart phone could be used as the (or one of the) touch interfaces of the videoconference.

In further embodiments, the touch interface (e.g., especially for the embodiment of FIG. 3B) may be usable outside of (or independently from) the videoconferencing system. For example, the touch interface may be used to perform audioconferencing without using all (or some of) the various additional components of the videoconferencing system. Thus, in one embodiment, the speaker phone of FIG. 3B may be used to perform audioconferencing.

As shown in these Figures, the touch interface may be a touch display that is configured to display graphics on the display as well as receive touch input. For example, as shown, the touch display may display a graphical user interface. For example, a user may be able to select various icons or graphical buttons displayed in the graphical user interface to perform videoconferencing actions.

A user may be able to provide gestures to the touch interface to perform videoconferencing actions. As used herein, a “gesture” refers to a touch interaction with a touch interface. A gesture may include the use of one finger (or digit), two fingers (e.g., to perform two simultaneous touches), three fingers, four fingers, five fingers, etc. A gesture involving one touch (e.g., by a single finger or digit) may be referred to as a “single-touch gesture” and a gesture involving more than one touch (e.g., by a plurality of fingers or digits) may be referred to as a “multi-touch gesture”. Generally, a gesture is begun by initiating a touch and is ended when the touch is no longer present (e.g., when there is no longer any touch on the touch interface or when the initial touch is no longer on the touch interface).

Exemplary gestures include a single touch (e.g., a “tap” with a single finger), a double touch (e.g., a “double tap” with a single finger), a two finger touch (e.g., a “tap” using two fingers simultaneously), a three finger touch, a four finger touch, a five finger touch, an expansion gesture (e.g., a “reverse pinch” or “spread” where two touches are initiated and then the distance between the two touches are increased while both remain in contact with the touch interface, although more than two touches may be used, e.g., with three touches where at least one touch moves away from the other two touches), a minimization gesture (e.g., a “pinch” where two touches are initiated and then the distance between two touches are decreased while both remain in contact with the touch interface, although more than two touches are envisioned), a “drag” or “slide” gesture using one or more touches (e.g., where a single touch is initiated, then moved some distance along the touch interface, and then released), a “flick” gesture using one or more touches (e.g., where a touch is initiated and then quickly moved along the touch interface and released), a “press” gesture (e.g., where one or more touches are initiated and then held for a threshold amount of time, longer than a tap gesture), a “press and tap” gesture (e.g., where one or more touches are “pressed” and then a second one or more touches are “tapped”). In some embodiments, gestures may include drawing or outlining. For example, a user may provide a gesture by touching the touch interface and then drawing a shape (e.g., an “L”, backwards “L”, a circle, a square, or any type of shape or sequence of lines). The user may create the shape using any number of simultaneous touches (e.g., using one finger, using two fingers, etc.) and each may be distinguishable from the next based on the number of touches and drawn shape. Thus, gestures may include outlines or drawings of shapes. Generally, gestures described herein are more complex than simple single touch tap gestures. These gestures may be referred to as “complex gestures”. Accordingly, as used herein, a “complex gesture” is any gesture other than (or more complex than) a single touch tap. Generally, a complex gesture includes a single touch and additional touch input (e.g., such as another touch for a two touch tap, additional movement for a drag, increased time for a “touch and hold” gesture, etc.). Additionally, any instance of a “gesture” used herein may refer to a “complex gesture”.

In one embodiment, the gestures may be provided to a portion of the touch interface that is dedicated to gestures or may be provided in response to selecting a gestures button (e.g., in order to indicate to the touch interface that the user wishes to provide a gesture). However, in alternate embodiments, the gestures may be provided over the graphical interface. In such embodiments, the gestures may be used to indicate or perform a videoconferencing action that is not indicated in the graphical user interface. More specifically, the gestures may indicate the videoconferencing action independent from what is displayed on the touch display. In further embodiments, the touch interface may not include a display, and gestures may simply be provided to the touch interface.

Thus, a user may be able to interact with or control a videoconference using the touch interface of FIGS. 3A and 3B.

In further embodiments, the touch interface may provide features in addition to the controlling videoconference. For example, the touch interface may be used to display video of the videoconference (e.g., duplicating video that is displayed on the videoconferencing system's display or video that is not provided for display in the videoconferencing system). When displaying video, the touch interface may provide the video at a lower resolution and/or frame rate than the videoconference display(s) (e.g., which may operate at high definition). For example, the touch interface may display at a 5-10 frames per second (fps), although other frame rates are envisioned.

In one embodiment, the touch interface may be used to display a presentation while the videoconference display provides video of participants of the videoconference. For example, a user may be able to upload a presentation to the touch interface and then control the presentation via the touch interface. In another embodiment, a user may select to view a presentation provided by another user on the touch interface. Alternatively, the touch interface may be used to display video of participants, e.g., while a presentation is provided for display on the videoconference display(s). Any type of video may be provided for display on the touch interface, as desired.

Additionally, the touch interface (whether combined with the speaker phone as in FIG. 3B, or not, may be used as a mini videoconferencing system. For example, a user may be able to perform an audioconference using the speakerphone and then provide a presentation during the audioconference by using the touch interface, e.g., after using a USB thumb drive to upload the presentation to the touch interface. Thus, the touch interface may be configured to provide a video stream of the presentation to other participants, thereby acting as a videoconferencing system. Similarly, a camera may be used (e.g., integrated with the touch interface or speakerphone) and accordingly, the images captured by the camera may be provided to other participants of the videoconference. Thus, the touch interface may be used as a mini videoconferencing system in addition to acting as a component of the videoconferencing system, such as that shown in FIG. 1. Note that video may take a lower priority than audio in such an embodiment.

FIG. 4—Controlling a Videoconference Using a Touch Interface

FIG. 4 illustrates a method for controlling a videoconference using a touch interface. The method shown in FIG. 4 may be used in conjunction with any of the computer systems or devices shown in the above Figures, among other devices. In various embodiments, some of the method elements shown may be performed concurrently, performed in a different order than shown, or omitted. Additional method elements may also be performed as desired. As shown, this method may operate as follows.

In 402, a first gesture may be received to a touch interface. The first gesture may be any of the gestures described above, regarding FIGS. 3A and 3B, although any type of gesture is possible. Additionally, the first gesture may be received to the touch interface in any of various manners. For example, as indicated above, the touch interface may include a graphical user interface for controlling a videoconference. The user may interact with the graphical user interface by performing a tap gesture to select various options displayed in the graphical user interface. In one embodiment, the first gesture may be performed over the graphical user interface and, e.g., may be independent from the various options presented in the graphical user interface, as described below. Alternatively, the gesture may be provided within a “gesture” portion of the touch interface, in response to selecting a “provide gesture” option, etc. Further, the gesture may be interpreted based on the current options in the graphical user interface of the touch interface.

In 404, a first videoconference action may be performed in response to the first gesture. For example, the touch interface may receive the gesture in 402 and then provide an indication of the gesture to the videoconferencing system (e.g., to a videoconferencing unit of the videoconferencing system).

The particular combination of gesture and videoconference action may be any desired combination. As discussed below, the gesture and action may relate to performing various volume control actions, muting, controlling a videoconference camera, and/or accessing settings (e.g., administrative settings for the videoconference or videoconferencing system). Other pairings are envisioned and may be used for any desired videoconference action. For example, further videoconferencing actions that may be controlled include controlling the current slide in a presentation (e.g., a two finger swipe to move forward or backward in the presentation), adding or removing participants, changing layouts, promoting participants, answering calls, enabling or disabling do not disturb, selecting a new input, starting or stopping a presentation, getting help, performing call transfer, putting a call on hold, VOIP use or login (e.g., Skype® login or Presence Status Changes), interacting with remote systems, such as bridges or MCUs, etc.

The first videoconference action may be determined based only on the first gesture itself. More specifically, as indicated above, the first videoconference action may be determined from the first gesture independent from a graphical user interface (or any information) displayed on the touch interface. For example, the graphical user interface may currently display options for presentations and the first gesture may be for muting the videoconference (although any other videoconference actions are possible). Accordingly, despite the context of the graphical user interface, the first gesture may perform the mute action. Thus, in this embodiment, the first videoconference action may be determined independent from the information displayed on the touch interface.

Alternatively, the first videoconference action may be based on the context of the first gesture. For example, the first gesture may be associated with a plurality of different actions and the method may determine which of the actions based on the context of the first gesture. Following the example above, the first gesture may be associated with a presentation (e.g., to move forward or back in a presentation) but may also be associated with a different action, e.g., controlling a camera. Accordingly, the method may determine that because a presentation is currently being given, because the current graphical user interface relates to presentations, etc. the first gesture is to perform the presentation action rather than the camera control action. The context may include whether the user input is received during a videoconference, whether the user input is received during a presentation, whether the user input is received during boot time or start up time of the videoconferencing system, a current graphical user interface (e.g., of the touch interface or of the videoconferencing display), a current menu being displayed (e.g., based on the subject of the menu, such as a presentation menu, in call menu, settings menu, participants menu, etc.), layout selection, input selection, remote system interaction (e.g., for bridge or MCU), call statistics, call transfer, etc. Thus, in some embodiments, the videoconference action that is performed may be determined based on the context in which the first gesture was received.

In 406, a second gesture that is different from the first gesture may be received to a touch interface. Accordingly, in 408, a second, different videoconference action may be performed in response to the second gesture. The second gesture and second videoconferencing action may be received and performed in a manner similar to the first gesture in 402 and 404.

Exemplary gestures and actions are provided below in FIGS. 5-8. However, these are provided as examples only and other gestures and actions are envisioned. Additionally, the embodiments and variations described above apply to the gestures and actions of the following descriptions.

FIG. 5—Muting a Videoconference in Response to a Gesture

FIG. 5 illustrates a method for muting a videoconference using a touch interface. The method shown in FIG. 5 may be used in conjunction with any of the computer systems or devices shown in the above Figures, among other devices. In various embodiments, some of the method elements shown may be performed concurrently, performed in a different order than shown, or omitted. Additional method elements may also be performed as desired. As shown, this method may operate as follows.

In 502, a gesture may be received to a touch interface to mute a videoconference. The gesture may be any desired gesture, e.g., from those described above, among other possibilities. For example, the gesture may be a two finger tap and/or a three finger tap, although other possibilities are envisioned.

In 504, the videoconference may be muted in response to the gesture. In some embodiments, the mute may be a “video mute” where the video provided from the participant location/videoconferencing system that received the input is no longer provided (or is provided as a blank or black screen). Alternatively, or additionally, the mute may be a “audio mute” where the audio provided from the participant location/videoconferencing system that received the input is no longer provided (or is otherwise silenced). In one embodiment, these two mutes may be separately controlled or activated using different gestures. For example, the audio mute may be invoked using a two finger tap and the video mute may be invoked using a three finger tap. Alternatively, or additionally, both mutes (or an “all mute” action) may be activated via a single gesture.

The audio mute and/or video mute may also mute the incoming audio or video from other participants. For example, when the audio mute is invoked, the audio from other participants may be silenced for the participant location/videoconferencing system that received the gesture. However, similar to above, the muting of incoming audio and/or video may be controlled via separate gesture(s) (e.g., one for each incoming mute or one for both, as desired).

FIG. 6—Adjusting Volume of a Videoconference in Response to a Gesture

FIG. 6 illustrates a method for adjusting volume of a videoconference using a touch interface. The method shown in FIG. 6 may be used in conjunction with any of the computer systems or devices shown in the above Figures, among other devices. In various embodiments, some of the method elements shown may be performed concurrently, performed in a different order than shown, or omitted. Additional method elements may also be performed as desired. As shown, this method may operate as follows.

In 602, a gesture may be received to a touch interface to mute a videoconference. The gesture may be any desired gesture, e.g., from those described above, among other possibilities. For example, the gesture may be a multi-touch vertical drag (e.g., touching with two touches and dragging vertically up or down and then releasing). However, other types of gestures are envisioned. For example, horizontal dragging gestures may be used.

In 604, the volume of the videoconference may be adjusted in response to the gesture. For example, the volume may be adjusted higher based on the gesture being an upward gesture. Similarly, the volume may be adjusted lower based on the gesture being a downward gesture.

The degree to which the volume is changed may be based on a characteristic of the gesture, such as the length or magnitude of the gesture. For example, smaller gestures may result in a smaller change in volume than larger gestures. Thus, a user providing a gesture which has a vertical length of 0.5″ may have a smaller change in volume than one with a vertical length of 1″.

As another example, the characteristic may be the length of time the gesture is held. For example, the user may provide an upward swipe with two touches, which may result in the increase of volume by a predetermined increment (likewise a downward swipe may result a decrease in volume by the predetermined increment). However, the user may elect to hold the gesture and the length of time may be used as the characteristic for determining the amount of change in volume. For example, the volume may increase or decrease an increment for every 0.25 seconds, 0.5 seconds, 1 second, etc. that the gesture is held (e.g., before release of the gesture). The determination of change in volume may be linear with respect to the characteristic of the gesture, exponential, geometric, or any desired mathematical relationship. Thus, as one example, the longer the length of the gesture or the longer the gesture is held (among other possible characteristics), the faster the volume may change.

Thus, in FIG. 6, volume for the videoconference may be modified based on a gesture received to a touch interface.

FIG. 7—Controlling a Camera of a Videoconference in Response to a Gesture

FIG. 7 illustrates a method for controlling a camera of a videoconference using a touch interface. The method shown in FIG. 7 may be used in conjunction with any of the computer systems or devices shown in the above Figures, among other devices. In various embodiments, some of the method elements shown may be performed concurrently, performed in a different order than shown, or omitted. Additional method elements may also be performed as desired. As shown, this method may operate as follows.

In 702, a gesture may be received to control a camera of a videoconference. The gesture may be any desired gesture, e.g., from those described above, among other possibilities. For example, the gesture may include a drag gesture (e.g., with one or more touches) to direct the camera to change its position. As another example, the gesture may include a multi-touch gesture (e.g., a pinch or reverse-pinch gesture) to modify the zoom of the camera. As a further example, the gesture may include a multi-touch gesture (e.g., expanding or collapsing, using more than two fingers) to modify a focus of the camera. The gesture may be used to control any of various cameras, e.g., a local camera of the participant location, a far-end camera of another participant's location, etc. In some embodiments, different gestures may be used to control different cameras (e.g., where the number of touches indicates the desired camera, or where a pre-gesture indicates which camera the gesture applies to). Thus, a gesture may be received to control a camera.

In 704, a camera may be controlled in response to the gesture. As indicated above, in response to a drag gesture (e.g., using one or more touches), the camera may be correspondingly moved. For example, if the user provides a vertical drag gesture, the camera may move up or down in the same direction as the vertical drag (e.g., if the gesture was vertically up, then the camera may be tilted up). As another example, if the user provides a horizontal drag gesture, the camera may move left or right in the same direction as the horizontal drag. The gestures may not be limited to solely horizontal or vertical gestures—for example, an angled drag (e.g., from bottom left to top right) may result in an upward tilt and rightward pan, at the same time. In some embodiments, the camera movement may be the inverse of the provided movement (e.g., in response to the user enabling an “invert axis” option), where an upward drag results in a downward tilt. In some embodiments, the inversion may only be performed for the y-axis and not the x-axis, although other embodiments are envisioned (where both axis are inverted). Similar to the volume control embodiments discussed above, the degree of movement may be based on the size or magnitude of the drag, according to any of various mathematical relationships.

FIG. 8—Accessing Settings of a Videoconference in Response to a Gesture

FIG. 8 illustrates a method for muting a videoconference using a touch interface. The method shown in FIG. 8 may be used in conjunction with any of the computer systems or devices shown in the above Figures, among other devices. In various embodiments, some of the method elements shown may be performed concurrently, performed in a different order than shown, or omitted. Additional method elements may also be performed as desired. As shown, this method may operate as follows.

In 802, a gesture may be received to a touch interface to access settings of the videoconference. The gesture may be any desired gesture, e.g., from those described above, among other possibilities. For example, the user may provide a large number of touch tap gesture (e.g., a four or five finger tap) to access the settings, although other types of gestures are envisioned

In 804, a settings interface of a videoconference may be displayed in response to the gesture. For example, the settings interface may be for the current videoconference, for the videoconferencing system in general, or for any desired settings. The particular settings interface shown may be context dependent. For example, a same gesture may be used to invoke the settings interface, but the particular settings interface shown may depend on the context in which the gesture was received. For example, a settings interface of the videoconference may be displayed if a videoconference is in progress, a settings interface of the videoconferencing system may be displayed when a videoconference isn't in progress or as a default, a lower level (e.g., firmware) settings interface may be displayed if the gesture is provided during a boot or reboot, etc. Further, the gesture may be interpreted differently if it is provided in combination with other input. For example, the firmware settings may be displayed only when the gesture is provided during a reboot and a light sensor is flooded (e.g., using a flashlight). Thus, the settings interface may be context dependent. However, in alternate embodiments, different gestures may be used for each different settings interface. Additionally, after providing the gesture, the system may prompt the user for a password to access the settings interface.

The settings interface may be provided for display on the touch interface and/or on the display of the videoconference, as desired.

The settings gesture may be particularly beneficial so that the typical graphical user interface does not have to be cluttered with options that only administrators or IT professionals require. Additionally, the administrators may appreciate that users may not be aware of or may be unable to access (and therefore may be unable to modify) these settings, which may result in a more consistent and desirable operation of the videoconferencing equipment during videoconferences.
